Abstract
The electronic structures of quantum dots with 6, 9, and 13 electrons under the influence of a strong magnetic field together with a positive impurity has been studied. By diagonalizing the Hamiltonian and by a detailed analysis of the wave functions, both crystal-like and liquidlike states were found. The crystal-like states have clear core-ring structures. The effect of impurity and the effect of symmetry constraint on these structures has been clarified. Based on the symmetry constraint, the states can be well classified, and the candidates of magic angular momenta can be predicted.
